Permanent URI for this collection
The Australian Passive Seismic Server (AusPass) is a service dedicated to the acquisition, management, and distribution of passive seismological data in Australia. Extensive fieldwork projects are conducted across the country, organized in seismic arrays (i.e. groups of seismic stations).

Item Open Access The SKIPPY seismic array: Exploring the Seismic Structure in 3D beneath Australia(Australian Passive Seismic Server (AusPass). Australian National University, 1996) van der Hilst, Rob; Kennett, BrianThe SKIPPY experiment [Van der Hilst and Kennet, 1993] was conducted between January 1993 and December 1996 to explore the three-dimensional structure of the Earth's mantle and lithosphere beneath the Australian continent. SKIPPY was a the first transportable array aiming at covering the Australian continent with stations spaced by about 400 km. During each stage of the experiment, 8 to 12 brodband seismometers (Guralp CMG-3ESP and Reftek) were deployed across different regions of Australia. The motion of arrays from region to region led to the name Skippy, following the iconic Aussie TV series "Skippy The Bush Kangaroo".Item Metadata only Southern Queensland Spiral Array(Australian Passive Seismic Server (AusPass). Australian National University, 2014) Stipcevic, JosipSQSPA is a three arm spiral array. This array was an experimental array designed to enhance weak signals and identify the local character of the wavefield. It consists of 16 trillium compact 120s seismometers and has an array radius of approximately 25 km.Item Open Access AuSIS : Australian Seismometers in Schools(Australian Passive Seismic Server (AusPass). Australian National University, 2011) Australian National UniversityAustralian Seismometers in Schools (AuSIS) is a dual purpose seismic network. The program offers both education outreach and provides quality data for monitoring and research. AuSIS is part of the international Seismographs in Schools (SIS) program supported by IRIS (Incorporated Research Institutions for Seismology). In January 2019, AuSIS counted 50 permanent seismic stations in Australia. This number might grow as new Australian schools are integrated in the program every year. We use Guralp CMG-6TD seismometers and stream live data to the schools and Geoscience Australia. Passive broadband seismic data ata are also provided through the IRIS and AusPass data centers.Item Open Access BASS: Seismic deployments across the Bass strait from 2011 to 2013(Australian Passive Seismic Server (AusPass). Australian National University, 2013) Reading, Anya; Rawlinson, NickFrom May 2011 to April 2013, 24 broadband stations were deployed from southern Victoria to northern Tasmania to illuminate the 3-D structure of the crust and lithosphere beneath the Bass strait. The BASS experiment was undertaken under a collaborative effort of several organizations including The Australian National University, the University of Tasmania, FROGTECH, Geological Survey of Victoria, and Mineral Resources Tasmania. The seismic data recorded during the BASS experiment consist of approximately two years of ambient seismic noise continuously recorded at 24 stations located in northern Tasmania, several islands of the Bass Strait (King Island, Deal Island and Flinders Island) and southern Victoria. The microseisms occuring in the Bass Strait and the influence of the Southern Ocean provided a vigorous and relatively consistent distribution of noise sources during the experiment. Guralp CMG-40T seismometers were used with Earth Data digitizers at a sampling rate of 50 Hz.Item Open Access CAPRAL: Seismic deployments in Northwest Australia from 2005 to 2008(Australian Passive Seismic Server (AusPass). Australian National University, 2008) Reading, Anya; Kennett, BrianThe CAPRAL array was designed to improve local earthquake location and hence understanding of neotectonics in northwestern Australia. These stations provide a useful framework to improve coverage of the Pilbara craton and the Capricorn orogen. The array consists of 27 site with Guralp CMG-3ESP seismometers and Earthdata digitisers. Sample rates are 25 samples/sec. CAPRAL (Capra + Linkage) stations provide all together a useful framework to improve the coverage of the Pilbara craton and the Capricorn orogen. Guralp CMG-3ESP seismometers and Earthdata digitisers were used with sampling rates of 25 samples/sec.Item Open Access WACRATON: Seismic deployments in Western Australia 2000-2001(Australian Passive Seismic Server (AusPass). Australian National University, 2001) Kennett, BrianThe WACRATON array was designed to explore the changes in the crustal structure of Western Australian cratons. The deployment of broadband instruments in 2000 - 2001 provides an improved coverage of the western part of the continent, where few geophysical investigations are carried out. Surface wave paths were used to compensate for equipment problems encountered in the later stages of the SKIPPY project. Instruments included Guralp 40T and 3ESP sensors, a STS2 sensor, and Orion and Reftek digitisers. Data was sampled at 25 samples/sec.Item Open Access The SOC seismic array: Structure Of Cratons (2007-2008)(Australian Passive Seismic Server (AusPass). Australian National University, 2008) Fontaine, Fabrice; Kennett, BrianAustralia is characterized by several cratons and orogens. SOC [Fontaine, 2007] was deployed from Jan. 01, 2007 to Aug. 14, 2008 to characterize the structure of the Gawler and Curnamona cratons. Guralp 40T and 3ESP sensors were used with Orion and Earthdata digitisers operating at 25 samples per second. The principal objective of the SOC experiment was to determine the transition between the Precambrian lithosphere and the Phanerozoic lithosphere in South Australia. The nature of the basement beneath the Lachlan Orogen and the number of ancient subduction zones are indeed still debated. Specific goals were to: determine the plate and the crust thicknesses with receiver functions analyses, constrain the deformation of the crust and the upper mantle using seismic anisotropy, increase the coverage of previous seismic deployments in South East Australia to improve the 3-D images of the crust and upper mantle by body wave and surface wave seismic tomography.Item Open Access KIMBA98: Seismic deployments in the Kimberley Region(Australian Passive Seismic Server (AusPass). Australian National University, 1998) Kennett, BrianFrom May to October 1998, a second seismic deployment was conducted in Kimberley, including the remote northern part of the region. The same type of instruments were used (Guralp CMG-3ESP and Reftek) and the station locations were chosen to improve the coverage of the region.Item Open Access KIMBA97: Seismic deployments in the Kimberley Region(Australian Passive Seismic Server (AusPass). Australian National University, 1997) Kennett, BrianFrom July to October 1997, a set of broadband instruments were deployed in the Kimberley region, on the King Leopold and Halls creek fold belts, as well as the interior of the block. The array was designed to build on the information gained from SKIPPY and to improve knowledge of a region where very little geophysical investigation was available. The instruments used were the Guralp CMG-3ESP and Reftek recorders.Item Open Access The BILBY Seismic Array: Exploring the Australian Cratonic Lithosphere(Australian Passive Seismic Server (AusPass). Australian National University, 2011) Rawlinson, Sara; Kennett, BrianThe BILBY array [Rawlinson, 2008] consists of 25 broadband seismic stations (Guralp 3ESP sensors) deployed between August 2008 and February 2011 along a North-South transect extending over 1000 km across central Australia (red squares on the map). BILBY was designed to investigate the transition in the lithosphere between the northern and southern Australian cratons and across parts of the intercratonic suture belts. BILBY connects the Gawler Craton in the south to the Mt. Isa Block in the north through the Musgrave and Arunta Blocks. An analysis of the seismic data aquired with BILBY showed three distinct Moho discontinuities in this complex region, the northernmost of which was previously unknown [Sippl, 2016].
